You are kind of a folk hero for us. Quite literally, you were the first
to give us a kind introduction to the Planck Length back in 2012.

In the process of helping a nephew (math/geometry teacher), we began
chasing embedded geometries (tetrahedron and octahedron) by dividing
the edges by 2 and connecting those new vertices. In 45 steps we were
down into the CERN-scale. In another 67 steps within, we were down
into the Planck scale.

We had to learn a little about the Planck scale, Planck Length, and base-2 exponentiation. Could we meaningfully multiply this numbers by 2 because in about 90 additional steps (total of 202 notations), we were out to the age and size of the universe.

We thought it was a neat home-grown STEM tool until we began
thinking about those first 64 notations in light of the rather remarkable
Wheat & Chessboard story. In reviewing the emerging literature
of the infinitesimally small, everything from strings, pions, and quarks,
to topos theory, Langlands conjectures, and so on, it seemed that
this rather “extraordinary place for mathematical purity” (that’s my
euphemistic expression) was not being respected for its potential
diversity.
